to allow for the thermal expansion or contraction
The distance between railway lines varies depending on the type of railway track and the country. 60 percent of railway lines in the world, however, use the 1,435 mm standard gauge.
The key element in railway lines depending on the railway line is, occasionally copper, magnesium and stainless steel.
C-Mn steel
There are two types of rail jointed and continuous welded rail. (CWR) In a jointed rail gaps are left to allow the rail to expand this is what causes the clackaty clack noise when on train. With continuous welded rails they are anchored very securely to prevent buckling.
Iron is rarely used anymore in railway lines. Steel is used mostly now because it is very flexible and is less vulnerable to cracking and chipping.
because of expansion and contraction.
no it doen't because there is little gaps in between and when it gets hot is expands and makes a full. track
Russia has the biggest longest range of railway lines.
Marine Lines railway station was created in 1867.

gaps in the middle of lines.
Railway tracks electrical lines
There are no railway lines in Wayanad district at kerala..It is the only district without railway line
The size of the gaps between railway sections decreases on a hot day. This is due to thermal expansion. Nowadays different composites are used and different methods employed when laying track so 'continuous' rails may be laid.
The place where two or more railway lines meet is called a rail junction.
Meghalaya & Sikim has no railway lines.
It depends which gaps you mean! Older track was laid in discrete sections with gaps left between them to allow for expansion on hot days. There are gaps between rails at the points which are used to connect different tracks together in turn. Is this what you mean?
